摘要
利用广东省林业科学研究院选育的的龙脑樟优良品系在广东平远县进行推广应用,根据对营建的平远县石正镇的龙脑樟推广示范林调查数据进行分析,结果显示龙脑樟林长势良好,种植后4a,林木保存率达91.2%,平均高2.75m、平均地径5.30cm、平均冠幅1.52m、平均单株采收枝叶11.75kg;经过实际调查与评估,第4年起可通过销售枝叶获得利润,项目净现值为1735.34元(折现率为0.05的情况下),内部收益率为25.54%、投资利润率为16.59%,静态投资回收期为3.94a、动态投资回收期为4.07a。分析结果说明龙脑樟种植业可取得较好的经济效益,因此建议平远县依托当地的龙头加工企业大力发展龙脑樟种植业,促进地方经济发展。
